Pokemon has never been about accuracy, pokemon is about variety. From concept to art style, from proportions to colours, from small to big, from ugly to pretty, from the stupid to the intelligent.
They exist in the same universe BECAUSE of that variety, and it is in fact you who is too narrow minded to see that. Pokemon =/= IRL so stop thinking that anything you see in Pokemon has to be thematic or synonymous the whole way through, or even on any kind of stable trend of development AT ALL.
Besides, when they're all turned into models you literally cannot tell what came from where. You need to stop breaking the pokemon down into gens and start seeing them as a whole. If you threw them into a shaker and randomized how the list looked as a whole you wouldn't be able to tell AT ALL. Because guess what you've done? Instead of trying to show progression, you get to see that the whole point of pokemon is to have variety in total.
Why should it stay the same for you to feel better about the game? It's NOT your game, if you want to make a game with a constant boring trend with less variety then go ahead and fucking make it. Nobody is stopping you.
